In the Linux kernel, the following vulnerability has been resolved:
ima: Fix stack-out-of-bounds in is_bprm_creds_for_exec()
KASAN reported a stack-out-of-bounds access in ima_appraise_measurement
from is_bprm_creds_for_exec:
BUG: KASAN: stack-out-of-bounds in ima_appraise_measurement+0x12dc/0x16a0
Read of size 1 at addr ffffc9000160f940 by task sudo/550
The buggy address belongs to stack of task sudo/550
and is located at offset 24 in frame:
ima_appraise_measurement+0x0/0x16a0
This frame has 2 objects:
[48, 56) 'file'
[80, 148) 'hash'
This is caused by using container_of on the *file pointer. This offset
calculation is what triggers the stack-out-of-bounds error.
In order to fix this, pass in a bprm_is_check boolean which can be set
depending on how process_measurement is called. If the caller has a
linux_binprm pointer and the function is BPRM_CHECK we can determine
is_check and set it then. Otherwise set it to false. (NVD)
